Hepatitis C virus genotypes 1–3 infections regulate lipogenic signaling and suppress cholesterol biosynthesis in hepatocytes

Journal of the Formosan Medical Association, 2020
Background: Patients with different hepatitis C virus (HCV) genotype infections are associated with varying metabolic disorders. Although alteration of lipid metabolism has been confirmed as a virus-induced metabolic derangement in chronic hepatitis C ...

Layer‐Specific Dermal and Subcutaneous Delivery via Modular LNP–Hydrogel‐Integrated Threaded Microneedles

Advanced Science, EarlyView.
Guided by spatial transcriptomics and clinical validation, a threaded microneedle platform enables precise layer‐specific delivery across the dermis and subcutaneous tissue. By addressing distinct pathogenic remodeling in different skin layers, this strategy coordinates compartment‐specific intervention, restores tissue architecture, and offers a ...

Atypical antipsychotics alter cholesterol and fatty acid metabolism in vitro[S]

Journal of Lipid Research, 2013
Haloperidol, a typical antipsychotic, has been shown to inhibit cholesterol biosynthesis by affecting Δ7-reductase, Δ8,7-isomerase, and Δ14-reductase activities, which results in the accumulation of different sterol intermediates. In the present work, we

Inhibition of cholesterol biosynthesis by cholic acid

, 1959
The effects of dietary cholic acid on free, total and ester cholesterol levels in liver and serum, and on the relative rates of incorporation of acetate-1-C14 and mevalonic acid-2-C14 were investigated in the rat.

Association between cholesterol-phospholipid vesicles and cholesterol crystals in human gallbladder bile [PDF]

, 1989
Rapid aggregation of cholesterol-phospholipid vesicles in gallbladder bile seems to be the first event in the production of cholesterol crystals, a prerequisite for cholesterol gallstone formation.

Sex‐ and Time‐Resolved Physiological and Gut Ecosystem Responses to a Food‐Grade Microbiome‐Targeted Intervention in Collegiate Endurance Athletes

Advanced Science, EarlyView.
In collegiate endurance athletes, a 6‐week randomized CPYE intervention yielded time‐ and sex‐dependent shifts in field‐based cardiorespiratory, metabolic, and redox indices, accompanied by changes in gut multi‐omics profiles. An exploratory extension during intensified training generates hypotheses warranting future validation.

Rat liver acyl-coenzyme A:cholesterol acyltransferase: its regulation in vivo and some of its properties in vitro

Journal of Lipid Research, 1980
To gain insight into the role of the enzyme acyl-coenzyme A:cholesterol acyltransferase (ACAT) in cellular cholesterol homeostasis, its regulation in rat liver was investigated both in vivo and in vitro.

A schematic representation of various inhibitors that inhibit cholesterol biosynthesis.

, 2013
Cholesterol biosynthesis takes place by two pathways, namely, the Kandutsch-Russell and Bloch pathways. These pathways have common initial steps starting from acetate and branch out after lanosterol.

FTSJ3‐Mediated 2′‐O‐Methylation of HSPA5 mRNA Stabilizes BOP1 via SUMOylation to Drive DRP1‐Dependent Mitochondrial Fission and Fatty Acid Oxidation in Lung Squamous Cell Carcinoma

Advanced Science, EarlyView.
The RNA methyltransferase FTSJ3 drives lung squamous cell carcinoma progression by catalyzing 2′‐O‐methylation of HSPA5 mRNA, which stabilizes BOP1 through SUMOylation and activates DRP1/SREBP1‐mediated mitochondrial fission and fatty acid oxidation. Targeting this axis with liposomal siRNA potently suppresses tumor growth and metastasis ABSTRACT Lung ...

Upadacitinib Restrains the Pathogenic Fitness of CD4+ T Cells and Aberrant B Cell Programming in Optic Neuritis

Advanced Science, EarlyView.
Single‐cell profiling and functional perturbation reveal coordinated JAK1‐pSTAT3 downstream programs in optic neuritis, including MCL1‐dependent fitness of pathogenic CD4+ Tem cells and glycolysis‐linked, cholesterol‐sensitive B‐cell responses associated with RORA. Upadacitinib disrupts this reciprocal T‐B‐cell circuit and alleviates neuroinflammation,
